17 Essential Tips for Buying Property
Go through these 17 tips carefully and review each point with the utmost precision. Even a single overlooked aspect can cause financial damage amounting to tens or even hundreds of thousands of euros.
| Tip | ||
|---|---|---|
1 | Have sales agreement reviewed Have the preliminary sales agreement (compromis de vente) legally reviewed by a notary or lawyer to be on the safe side. No suspensive conditions included – buyer loses deposit if unable to proceed. After signing the compromis de vente, French law grants a 10-day cooling-off period (délai de rétractation) – you can withdraw with full deposit refund, no justification needed. The 10 days start the day after you receive the signed compromis by registered letter (lettre recommandée avec accusé de réception). Withdrawal must be sent by registered letter – email or verbal notification does not count. If day 10 falls on a weekend or public holiday, the deadline extends to the next business day. | |
2 | Check land registry and mortgages Check entries such as easements (servitudes), rights of way (droits de passage), or mortgages (hypothèques) at the Land Registry Office (Service de Publicité Foncière). Old easement discovered – neighbor has permanent right of way through garden. | |
3 | Finalize financing Ensure that your property loan (prêt immobilier) is approved before signing the final deed (acte authentique). Loan refused after preliminary contract – 10% deposit forfeited. | |
4 | Thoroughly inspect building condition Commission mandatory property diagnostics (diagnostics immobiliers obligatoires) and additional expert inspection. Need for electrical compliance upgrade discovered only after purchase – costly surprise. Mold behind furniture noticed only after moving in – health risk. Roof structure (charpente) infested with termites – structural expert required later. Hidden humidity in basement – expensive waterproofing (étanchéité) needed after purchase. Outdated boiler (chaudière) – replacement became mandatory. Asbestos (amiante) in old floor coverings – costly removal required. Single-glazed windows not detected – high heating costs in winter. Lead pipes – replacement unavoidable. Poor thermal insulation – energy rating (DPE) class underestimated renovation costs. Dry rot (mérule) discovered during renovation – supporting beams affected. Missing building permit (permis de construire) for veranda – legal issues after purchase. | |
5 | Evaluate condo fees & maintenance fund Contributions that are too low indicate insufficient reserves (charges de copropriété & fonds de travaux). €15,000 exceptional assessment due – maintenance fund insufficient. | |
6 | Check general assembly minutes Show planned works and conflicts in the condo association (procès-verbaux of assemblées générales). Facade renovation voted after purchase – unexpected €20,000 share. Planned assessment for roof renovation. Disputes within the homeowners' association (syndicat des copropriétaires). Upcoming renovations (e.g., collective heating system). Maintenance fund insufficient for planned measures. Dissatisfaction with or change of property manager (syndic). Usage conflicts (e.g., short-term rentals). Structural changes affecting common areas. Unpaid charges by other owners. Changes to the condo bylaws (règlement de copropriété). Legal disputes or judicial proceedings. | |
7 | Read the condo bylaws Defines what belongs to you – crucial for modifications or extensions (règlement de copropriété). Terrace extension must be removed – violation of bylaws. | |
8 | Identify upcoming maintenance Postponed maintenance (travaux à prévoir) will cost significantly more later. Deteriorated facade – obligation to participate in expensive renovation. | |
9 | Analyze Energy Performance Certificate Indicates future energy costs and renovation obligations (DPE - Diagnostic de Performance Énergétique). Property classified F – unexpected heating costs and mandatory renovation by 2028. | |
10 | Plan the property inspection professionally Record defects and meter readings in writing (état des lieux). Set key handover date early – otherwise thorough inspection impossible. Prepare handover report – verbal defects cannot be proven later. Check all rooms – unnoticed hidden defects (vices cachés) hard to prove later. Secure evidence with photos/videos – later defects unenforceable without proof. Bring witnesses – hard to enforce without confirmation. Record condition in writing – later damage hard to assign without evidence. Note meter readings – electricity/gas disputes over consumption. Document all keys and badges – missing items noticed too late. Describe defects precisely – 'normal wear' is vague, unclear liability. Set clear deadlines – 'soon' isn't enough, no response for months. Define responsibilities – confusion over who handles what. Clarify questions on site – misunderstandings noticed too late. Secure documents digitally – otherwise no basis for claims. | |
11 | Check home insurance Verify coverage requirements – crucial for water damage (assurance multirisque habitation). Water damage – insurance insufficient for condo requirements. | |
12 | Check tourist rental regulations Short-term rentals heavily regulated in Paris and major cities. Airbnb requires registration number – planned income model illegal without it. | |
13 | Understand general assemblies Know your rights and obligations within the condo association (assemblées générales). Elevator renovation approved – unexpected €8,000 share. | |
14 | Consider heritage protection regulations Limits modernization in protected areas (secteur sauvegardé or ABF - Architecte des Bâtiments de France). Balcony installation refused by heritage architect – value enhancement blocked. Wall modification rejected – open-plan concept not feasible. Luxury renovation forbidden – planned rent increase failed. Attic conversion prohibited – additional surface not approved. Modernizations only partially allowed – comfort remains outdated. Double glazing installation blocked – energy savings delayed. Division into units difficult – transformation to studios prohibited. Elevator installation prohibited – accessibility not achievable. Heritage approval processes lengthy – work delays due to reviews. Rental after renovation regulated – profitability drops. | |
15 | Check previous tenants and usage history Identify prior issues, e.g., neighbor disputes (troubles de voisinage). Noise disturbance disputes resurface – high stress factor. | |
16 | Calculate ongoing expenses Include realistic expenses beyond condo fees (charges courantes). Property tax (taxe foncière) underestimated – budget shortfall first year. Condo fees not fully considered – monthly burden higher. Property manager fees overlooked – ongoing expenses significantly higher. Maintenance fund too low – renovations paid personally. Maintenance costs ignored – property loses value. Insurance not factored in – no protection or costly later. Variable interest rate not accounted for – monthly payments rise unexpectedly. Residence tax changes – annual costs rise (for second homes). Heating costs increase due to poor energy rating – no buffer included. Rental vacancy not planned – financing becomes unstable. | |
17 | Plan your move-in strategy Coordinate renovations, furniture delivery, and moving (emménagement) efficiently. Double costs due to delayed move-in – hotel accommodation necessary. |
